Split Grommet Seal - 3/4in Hole

The Split Grommet Seal - 3/4in Hole by SEALS-IT is a critical weatherproofing component for any vehicle modification project involving electrical wiring, brake lines, fuel hoses, or hydraulic systems. Whether you're running custom engine bay harnesses, installing aftermarket gauges, or fabricating a complete interior rewire, cable and line routing requires reliable sealing to prevent moisture, dust, and contamination from entering sensitive areas. This split grommet design allows technicians to retrofit protection onto existing runs without breaking connections or completely disassembling installations—a time-saving advantage in complex builds.

The 3/4 inch hole diameter accommodates standard automotive cable bundles, wire looms, and tubing commonly found in EFI conversions, turbo installations, and custom wiring harnesses. The split design—meaning the grommet opens along one side—lets you clamp it around existing runs without threading cables through during installation, dramatically reducing labor time on tight engine compartments. SEALS-IT manufacturing ensures durable elastomer construction that resists heat cycling, oil exposure, and UV degradation, maintaining a reliable seal through years of daily driving and track use. The compact 3.25 x 0.3 x 4.1 inch profile fits easily into tight quarters where conventional one-piece grommets cannot be fitted.

Professional mechanics, engine builders, and fabricators rely on split grommet seals for rapid prototyping and retrofit installations where precision fitment and environmental protection cannot be compromised. Common applications include mounting holes in firewalls for custom harnesses, transmission tunnel passages, radiator support penetrations, and undercarriage routing on lifted or lowered vehicles. Installation is straightforward: position the split grommet around your cable or line bundle, align with the hole, and secure with the clamping mechanism—no special tools required. This product is essential inventory for any shop supporting performance builds, restorations, or electrical system upgrades demanding professional-grade sealing solutions.
